Question

In a certain school,260 students were present on monday,270 on tuesday,280 on wednesday,and 250 on thursday find the average number of students present on those four days

Answer 1

Answer:

The average number of students present are 265

Step-by-step explanation:

Given the number of students present on monday were 260, the number of students present on tuesday were 270 , the number of students present on wednesday were 280 , the number of students present on thursday are 250.

Now the numbers are 260, 270, 280, 250

We should basically find the average of these four observations

We know that the $Average=\frac{sum of the observations}{number of observations}$

sum of the observations is 260+270+280+250=1060

number of observations are 4

Average=  $\frac{1060}{4}$   =265
